Embodiment 1

[0026] Embodiment one is basically as attached figure 1 , figure 2 Shown:

[0027] A shaking device for quality control products, including a frame, on which a storage tray 1 is provided, and on the storage tray 1, grooves 2 for placing quality control products and fixing parts for fixing quality control products, the grooves are provided The directions of 2 are parallel to the axis of the turntable, and are all arranged along the horizontal direction. The number of grooves 2 is at least four, and the grooves 2 are distributed on the storage tray 1 with the center of the storage tray 1 as the axis at multiple circles at equal intervals, and the grooves 2 on each circle are distributed in a circular array. The storage tray 1 is embedded with a cylindrical heating net 3 , the heating net 3 is a resistance wire, and the heating net 3 is located between two adjacent grooves 2 . A buffer layer is bonded on the inner wall of the groove 2, and the buffer layer is a foam layer or ...

Embodiment 2

[0032] Embodiment two is basically as attached image 3 , Figure 4 Shown:

[0033] The difference between the present embodiment and the first embodiment is that the fixing member includes two arc-shaped snap rings 16 , one ends of the two snap rings 16 are hinged on the storage tray 1 , and the other ends of the two snap rings 16 are snapped together. The frame is horizontally slidably connected with a second slide plate 17, and the inner rod 5 is rotatably connected with a bearing 18. The bearing 18 is welded with the second slide plate 17, and the transmission rod 12 is fixedly connected with the inner rod 5 through the bearing 18.

[0034] When fixing the quality control product, the quality control product is located in the middle of the two snap rings 16, and then the two snap rings 16 are engaged with each other, and the quality control product is hugged and fastened, thereby fixing it. For quality control products whose length is greater than the depth of groove 2 o...

Embodiment 3

[0036] Embodiment three is basically as attached Figure 5 Shown:

[0037] The difference between this embodiment and Embodiment 1 is: a controller 19, an alarm 20, a timer 21 for recording quality control time, and a temperature sensor 22 for recording the temperature of the heating network 3 are installed on the frame, and the controller 19 is all electrically connected with the first motor 9, the second motor 11, the cylinder 15, the heating network 3, the alarm 20, the timer 21, and the temperature sensor 22. In this embodiment, the models of the controller 19 and the temperature sensor 22 are respectively PLC FX3GA-24MR-CM and LM35DZ.

[0038] During specific implementation, the opening and closing of the first motor 9 , the second motor 11 and the cylinder 15 are controlled by the controller 19 . When the heating temperature reaches the preset temperature, the temperature sensor 22 converts the temperature signal into an electrical signal and transmits it to the contro...

Abstract

The invention relates to the field of medical instruments, and discloses a quality control product shaking-up device. The device includes a rack, and a storage tray is arranged on the rack. A groove for placing a quality control product and a fixing piece for fixing the quality control product are arranged on the storage tray. The rack is provided with a first driving mechanism used for driving the storage tray to rotate. The first driving mechanism comprises a telescopic rod, the telescopic rod comprises an inner rod and an outer rod, one end of the inner rod is connected into the outer rod through a key groove to enable the inner rod to rotate with the outer rod and slide relative to the outer rod, and the other end of the inner rod is coaxially and fixedly connected with the storage tray. A first driving piece for driving the outer rod to rotate and a second driving piece for driving the inner rod to slide back and forth are arranged on the rack. The invention can solve the problemsof long time consumption, low efficiency and incapability of meeting the use requirements due to the adoption of a one-way rotation mode in the conventional blending instrument.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a quality control product shaking device. Background technique [0002] In the routine inspection method of blood samples in clinical medicine, the quality control product needs to be recovered at room temperature for more than 15 minutes after being taken out of the storage environment at 2-8°C, and then mixed manually (manually upside down and upside down not less than 20 times), and the parameters are tested on the machine. Blood samples also need to be manually mixed according to the above method. In this way, the pretreatment of quality control materials and blood samples cannot be standardized, thus affecting the accuracy and precision of the results. [0003] In order to solve the above-mentioned problems, Chinese patent (CN203849081U) discloses a standardized mixer for blood specimens and quality control products, which includes a shell and a base plate that are mated with...
